摘　　要：应用Z扫描技术,在波长532 nm,脉宽为21 ps条件下研究C70甲苯溶液的非线性光学特性。实验结果表明,C70甲苯溶液具有非线性吸收和自聚焦特性。当去除溶剂的影响后,发现C70本身具有自散焦特性。The NLO properties of C70 solution were studied by using Z-scan technique with laser pulses of 21 ps pulse-width at a wavelength of 532 nm.The results show that the C70 solution possesses nonlinear absorption and self-focusing property.We find that the C70 self should possesses a self-defocusing property when we eliminate the effect of the solvent.
